Specification of Letters Patent No. 6,089, dated February 6, 1849.

To all whom it may concern:

Be it known that I, WILLIAM COBB, of the city of Albany and State of NewYork, have invented a new and Improved Method of ConstructingCooking'R'anges, which I call Cobbs Cooking-Range and Hot-Air Furnace,whereof the following specification, with the drawings attached heretoforming part of the same, is a full and perfect description, viz:

In the drawings Figure 1 represents a front view of the range having thefront plate, containing the doors of the furnace and ovens, removed, andthe top plate raised up directly above its place, for the purpose ofshowing the interior construction of the apparatus. Fig. 2 represents ahorizontal section through the range in the line of the axis of thelower air fiues.

In both figures the channels for the flame smoke &c are colored red andthe fines for heated air colored blue.

A, B, C, D, E, G represents the body of the range rectangular in shape,of cast iron. Its dimensions to depend upon the extent of itsemployment, whether for small or large families and private houses orfor hotels &c. It is to be divided into furnace, ovens, five channelsand hot air flues in the manner shown in the drawings, which aresufliciently plain and obvious to enable any mechanic to understand itsarrangement and construction; by various iron partition plates andtubes; and its practical operation is as follows:

H is the furnace with its ash-pit H constructed for the consumption ofeither wood or coal. Fire being made therein, the flame and heated gasesturning over the top of the air flue 0 passes downward by the channel Lto the bottom channel M thence along it to the end channel N up which tothe nozzle O by which they are led to the chimney, or house flue.

The air to be heated is to be introduced (by proper pipes or tubesleading from the open air when convenient) into either or both aperturesQ Q and passes into the chamber or flue a, b, c, f surrounding thefurnace; from this chamber it goes by the pipes or cylindrical flues d,d, d, cl, into the chamber or fiue e, from the bottom of which by thepipe flues g, g, g, 9, it is conducted to the box flue 7t,--thence byupright pipe flues m, m, m, m, to box flue a, and thence through theorifice S through the top of the range, whence it can be carried byproper conductors to any part of the premises to be warmed. There isalso from the top of chamber 6, a pipe flue 2,, lying in the angleformed by the back of the range and the top of the ovens and extendingto box n. By means of the registers at .2 and 7c in the channel over theovens, the flame &0 can be distributed and regulated to the ovens J andK and the boilers placed as usual through the top plate of the range.

It will be seen from this description that the air taken in at Q is inits passage through the apparatus exposed to a very large heatingsurface; first from the walls of the furnace then from both the sides offire channel L and in its passage through the pipes (Z, (Z, (Z, (Z,which are surrounded by flame; thence in its passage through the finesg, g, g, g,h,m, m, m, m, and a,as well as through t, which are alsoentirely enveloped in the flame and heated gases from the furnace. It isobvious therefore that in addition to the ordinary functions of cooking&c this range has the means and facilities of heating a large volume ofair for the purpose of warming a houseuniting in an eminent degree thequalities of an economical cooking apparatus and a hot air furnace.

I do not claim the construction of air fines or passages whether belowor back of the fire chamber nor hot air fiues surrounded by fire orheated gases as original with me; but

I claim The special combination and arrangement of hot air and fire andheated gas channels and fines in connection with the heating andculinary apparatus of a cooking range or stove as herein described; notlimiting myself narrowly to the proportion nor precise form of parts setout in this specification.

WILLIAM COBB.
